Job description
🎮 We are Opus Major, a Paris-based game studio building a a cross-platform large scale multiplayer game based on a strong universe where music is the magic of the world.

Our mission is to make the world Jam Together 🎶

We believe games and music can amplify social bounds. Our first Opus is the child of these two social amplifiers.
We’re a small team of 30 Jammers with big ambitions: we care about craft, iterate fast, and build systems meant to scale, not just technically, but also creatively.

To support our next milestones, we’re looking for an SRE / DevOps Engineer to help us build strong production foundations: reliability, deployment quality, observability, and infrastructure automation 🚀

Feel free to apply even if you have a doubt about the aforementioned skills!

Why this role matters 🚀

  • At Opus Major, infrastructure is not “support”, it’s a key part of the product’s success.
  • As an SRE, you’ll help us to: keep systems stable and scalable as the game growsmake deployments safe and repeatableraise the bar on production readiness.
  • You'll be part of the Online Team and report to our Principal Online.
  • You’ll work with the entire production department, with real ownership over reliability topics.

Your future responsibilities and scope as a SRE / DevOps Engineer at Opus 🎮

  • Kubernetes & Production Infrastructure
  • Operate and improve our Kubernetes clusters (GKE) in production
  • Define best practices around exposure, networking, scaling, and rollouts
  • Improve reliability through strong operational standards

  • Infrastructure as Code & Automation
  • Build and maintain infrastructure using Terraform
  • Automate workflows to reduce manual work and improve consistency
  • Help define clean deployment pipelines and environment management

  • Monitoring, Alerting & Observability

  • Design alerts that are meaningful and actionable
  • Help us move toward SLO-driven reliability and better incident response

  • Collaboration & Enablement
  • Work closely with developers to make systems production-ready
  • Communicate clearly about trade-offs, risks, and priorities
  • Contribute to a culture of ownership, transparency, and continuous improvement

The profile we are looking for at Opus 👾

  • Required skills (must have)
  • Strong experience operating Kubernetes in production (debugging, networking basics, rollouts, exposure patterns such as Ingress/Load Balancers)
  • Proficiency with Google Cloud Platform (GCP) (especially GKE, IAM, networking fundamentals)
  • Solid background in Terraform / Infrastructure as Code
  • Observability: Prometheus + Grafana, meaningful alerting practices

  • What we value (Mindset)
  • You thrive in environments with ambiguity and ownership
  • You focus on what matters most: prioritization & production outcomes
  • You communicate proactively (especially in remote/async contexts)
  • You are transparent about constraints and unknowns
  • You enjoy building reliable systems, not just shipping features

  • Experience
  • 3+ years in SRE / DevOps / Infrastructure Engineering roles
  • Open to junior profiles if the mindset, ownership, and learning ability are a strong fit 🤩

Nice to have (but not necessary)

  • ArgoCD / GitOps workflows
  • Kustomize 
  • Golang
  • Experience in gaming / multiplayer services

  • Build infrastructure for a product where tech and creativity collide
  • Strong ownership, lots of autonomy
  • Early-stage environment where pragmatism, prioritization, and hands-on execution matter more than perfect specs or rigid processes
    • You’ll shape the foundations of a game meant to scale globally

Location & Remote policy

  • Paris, France
  • We are an office-first company and value regular in-person collaboration especially in our early-stage environment and for our studio where collaboration, fast iteration, and shared context matter a lot.
  • Remote arrangements (only in France) can be considered for this role on a case-by-case basis, depending on seniority, autonomy, and team fit.

  • Intro call with our HR (culture, role expectations, context)
